BUTTON-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 405,664, dated June 18,1889. Application filedMaroh 29, 1888. SerialNo. 268,842. (No model.)

To all whom it may concern;

Be it known that I, LOENDER O. EMERSON, of North Grafton, county of\Vorcester and State of Massachusetts, have invented an Improvement inButtoif-Setting Machines, of which the following description, in connection with the accompanying drawings, is a specification,like letters onthe drawings representing like parts.

II) This invention has for its object to improve that class ofbutton-setting machines wherein the button having a projecting shank isattached to a boot, shoe, or other article by a pronged metallicfastening, which is clinched to hold the button in place.

My present invention is an improvement on that described in UnitedStates Patent No. 368,141, granted to me August 9, 1887.

I have herein shown my improvements adapted to set what is known as theKempshall fastening; butwith slight modifications the machine hereindescribed might be employed to drive other usual forms of metallicfastenings.

One feature of my invention consists in the combination, with abutton-raceway and an intermediate button-guide, forming a continuationthereof, of an anvil anddriver and circularlymioving reciprocatingsegmental o transferrer to take the buttons singly from the button-guideinto position to have a fastener driven through the eye of the buttonand clinched on the anvil.

, Other features of my invention will be hereinafter pointed out in theclaims at the end of this specification.

Figure 1 in side elevation represents a button-settin g machineembodying my invention, the column being partially broken out to save 0space on the drawings; Fig. 2, a sectional detail taken through thework-support and the driver in the direction of their length, and alsoshowing some of the devices for moving the driver. Fig. 3 is a partialfront elevation,

4 5 partially broken out, of the machine shown in Fig. 1. Fig. i is anenlarged detail showing the lower end of the button-raceway, thetransferrer, and anvil, and the driver and worlcsupport, the said figureshowing a fastener by dotted lines in position to be acted upon. to bedriven into the eye of the button held above it. Fig. 5 is a right-handside elevation of Fig. 4; Fig. 6, a similar view toFig. 4, but with theparts in a diiferent position, the fastener being shown as having beendriven and clinched. 5 5 Fig. 7 is a section in the line 00, Fig. 6; andFig. 8, a top view of the work-support.

The frame-work to support the working parts is shown as composed,essentially, of a column A, a rigid head A bolted to it, and an uprightA to support the button-receiving hopper A, which is and may be of anyusual construction, the said hopper, as herein shown, containing anagitator composed, es sentially, of a hub 6, which is secured to a shortshaft 5, the said hub having a series of brushes'7, the shaft 5 beingoscillated, as will be described.

The fastenerfeeding mechanism B, its spring Z) and collar thework-support B grooved at its inner face to receive the| shaped driverB, the sector-lever B to engage the teeth B of the driver, theconnecting rod 13-", treadle O, and spring 0 and stop S to arrest thework-support in its downward 7 5 position, are and may be all as usual,the particular devices just referred to being common to United StatesPatent No. 311,033 and such parts being old and not of my invention neednot be herein further specifically described.

The work-support B as herein shown, is adapted to be raised and loweredby the friction against it of the driver and a friction device carriedby the driver, the said friction device consisting, essentially, of awasher, as 23, a spring, as 24, and a screw 22, screwed into a lug 21 ofthe driver, the said lug being extended through a slot in thework-support, as shown in Fig. 2.

In the machine described in the Patent No. c 311,033, referred to,'theupward movementof the work-support is stopped as soon as the latterarrives in contact with the material resting against the anvil above it.

\Vhenthe upward movement of the work- 5 support, it carrying upward withit the stock, is arrested by the anvil, the material is oftentimesmarrcd or injured; but to prevent this I have provided the shank of thework-support with a pin or projection t, which enters I00 a slot in astop t, connected, preferably in an adjustable manner, with the head A,the said stop being herein shown as slotted and as held in adjustedposition by a clamping-screw F. The head of the connecting-rod B isprovided with a pin b ,,which enters a slot in an arm or lever b,pivoted to the head A by a screw, as b. This arm 5 has jointed to it aconnecting-rod I), attached at its upper end to a slide-bar b adapted toslide on a guiderod 0, the said slide-bar having attached to or formingpart of it. a rack c, which engages the teeth of a pinion 12, fast onthe rear end of a short shaft 13, having its bearings in a sleeve 14: ofa face-plate 15, the said sleeve being held in place by a set-screw 16in a stand-like portion 66 of the head A. The shaft 13, at its frontend, beyond the said face-plate, has attached to it by a screw, as 17,the segmental transferrer f, it, as herein shown, being made as afinger, the outerportion of which is circular or are shape.

This transferrer moves closely to the front of the face-plate 15, and inits movement surrounds, as it were, a projection 18 of the saidface-plate, the said projection (see Figs. 6 and 7) having attach ed toits out-er side by a screw, as 6 the anvil e, shaped as common to thesaid Patent No. 311,033. The projection 18 (see Fig. 3) has its outer orright-hand edge concaved to receive in it one edge of the button. Theprojection 18 has attached to it by suitable screws, as 30, (see Fig.5,) a curved plate D, concaved at its inner side tofit the head of thebutton, the groove in the projection 18 and the concavity in the plate Dsubstantially fitting the head of the button, there being left betweenthe said block and the said plate a groove, as 8*, through which travelsthe shank 32 of the button d as it is being acted upon by the segmentaltransferrer, the said projecion 18 and the plate D constituting theguideway for the button in continuation of the button-raceway D.

The shaft 5 of the agitator below the bottom plate on of thebutton-receiving hopper has an arm 4,which is connected by link 3 to anelbow-lever c pivoted at 2 upon an ear 0, extended from the upright Athe opposite end of the said lever 0 having jointed to it a link 0 whichis in turn attached to the slide 19 the reciprocation of the said slidecausing the oscillation of the shaft 5 and its attached agitator.

The platem has connected to it the upper end of the raceway D, made,preferably, of sheet metal, and having a groove, as 8, to receive theshanks of the buttons, the said groove being preferably at the face ofthe raceway. This button-raceway D, near its lower end, has connected toit by screw 10 a detent D made as a spring, the lower end of which iscurved toward and so as to act upon the head of the button and stop theend most button of the column of buttons at the lower end of theraceway.

The groove in the raceway is substantially straight, and the transferrerherein shown is so shaped and actuated as to act upon the endmost buttonof the column and transfer it from the end of the raceway into theposition between the anvil and driver to receive through its eye thefastener.

Figs. 4 and 5 show the eye of the button turned toward the operator andin position to be entered by the prong of the fastener represented bydotted lines at b, Fig. 4.

This transferrer, the outer end of which moves in the arc of a circle,also serves as a stop for the endmost button of the column of buttonsduring the time that the transferrer takes a button from the column ofbuttons and carries it in position to be driven, the said transferrersupporting the endmost button of the column of buttons until thetransferrer returns nearly to its normal position. (Shown in Figs. (3and 7.) The button next to be attached by the transferrer is broughtinto the position shown in Figs. 4 and 5, and is left between aspring-support, as 6 and the projection 18, with one side of the shankof the button against one edge of the anvil 6, herein represented asfixed in position but located above the material, the open portion ofthe eye of the button being in line with the concavity of the saidanvil, the said spring 6. sustaining the button in the position left bythe transferrer while the usual driver actuated in usual manner isoperated to drive the point of the fastener being used through thematerial and through the eye of the button and against the anvil, as inFigs. 6 and 7, Fig. 6 showing the point of the fastener as clinchedthrough the eye of the button.

I have not herein shown the stock or material through which the fasteneris driven preparatory to entering the shank of the button. Herein thebutton is shown as taken from the button-raceway D, with its shankextended toward the operator, and the shank is kept in that position bythe transferrer while the button is being transferred from the end ofthe raceway to the anvil,- thereby enabling the open eye of the buttonto be kept towardthe operator, who can thus readily see whether or notthe point of the fastener is rising properly through the material tocorrectly enter the eye of the button. Such arrangement of parts wherebythe shank of the button'is kept toward the operator greatly facilitatesthe operation of the machine and enables the operator to run it atfaster speed, and at the same time do better Work.

\Vhen the eye of the button is turned toward the operator, the lattermay readily look through the eye of the button and see whether or notthe spot or mark applied to the upper to designate the point at whichthe prong of the fastener is to penetrate the stock is directly in linewith the opening in the said eye.

The plate 92 keeps the driver pressed toward the underside of thework-support.

I claim 1. In a button-setting machine, the combination of the followinginstrumentalities, viz: a raceway for the buttons, a raceway to guidefasteners, an anvil, a driver, a detent for the buttons in thebuttoirraceway, a button-guideway in extension of the raceway andlocated between the latter and the anvil, as described, and anindependent reciprocating segmental transferrer to take the said buttonssingly from the raceway to the anvil and driver into position to have afastener driven through the button-eye, substantially as described.

2. In a button-setting machine, the combination, with a raceway, anvil,and driver, of a circularly-moving reciprocating segmental transferrerand intermediate button-guide, the said transferrer transferring thebutton from the end of the raceway to the driver, substantially asdescribed.

3. The slotted raceway, the anvil, the driver, the button-supportin gspring located near the said driver, and the guideway interposed betweenthe button-raceway and the anvil, combined with a circularly-movingreciprocating segmental transferrer adapted to transfer the button fromthe raceway to the anvil, and to also act as a stop for the endmostbutton of the column of buttons in the button-raceway, substantially asdescribed.

4. In aZbutton-setting machine, an anvil and a driver, combined with averticallymovable work-support actuated by the said driver and with astop to limit the upward movement of the work-supp0rt toward the anvil,substantially as described.

5. In a button-setting machine, a buttonreceiving hopper, a slottedraceway in connection therewith, an anvil, a slotted buttonguidewayinterposed between the said anvil and raceway, and a work-support anddriver, combined with a segmental transferrer to transfer the buttonfrom the end of the raceway to the driver, the slots in tire raceway andin the guideway being constructed, substantially as described, to enablethe eye of the buttonto be presented toward the operator, in order thatthe latter may unerringly see whether or not the material and the eye ofthe button are in proper position to be entered by the prong of thefastener, substantially as described.

6. In a button-setting machine, the hopper,

the button-raceway slotted at its front side, i

and the button-guideway, also slotted at its front side, for theextension through the said slots of the shanks of the buttons, combinedwith the anvil and driver and with a se mental transferrer to take thebuttons from the button guideway with their shanks toward the operator,in which condition the open eye of the button is readily visible,substantially as described.

7. The buttonraceway, the button-guide, the transferrer, its shaft 13,and the driver, combined with the connecting devices between the saidrod and driver and between the rod and shaft 13, to actuate thetransferrer, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
